  1. Used to be able to buy folding cast aluminium ones from Brian Carter, don't know if he is still in business. (Long time Past Commodore of NZMYC, (multihull yacht club).) Cheers Tb
  2. Port Nick web site lagging, leg two finished but no results, maybe some still out there off hawke bay...

    Something Fishy

    We saw flying fish off Tom Bowling Bay last week as we went round the top. They fly a very long way....... Tb

    Old Pics

    I read a book by Wade Doak, the diver, who said that Mangroves were even planted around the Thames coast as they trap sediments and provide a fantastic nursery for all sorts of fish and crustacean life. Cheers
  5. M12 (or at a pinch old fashioned 1/2 inch which is 12.7mm). 13mm hole provides a small amount of clearance on 12mm Tb
  6. A bit of cross purposes talk going on here. Wireless Nation provide internet services using the cellphone networks. So no voice unless you can VOIP (voice over interent. Its a special type of modem. A cellphone booster takes the existing (maybe weak) cellphone signal, boosts it and then retransmits it so your cellphone can pick it up. No modem. We have a WN modem for our caravan and we added an external antenna (looks like a shark fin) which proves better coverage in marginal areas. The standard WN modem is a bit marginal unless you have a good signal strength (or the external a
  7. Typically you should expect to pay about $55/m2 for preparation and paint (two coats). Unfortunately a trimaran has a lot of square meters. haulage and hard stand on top sometimes. Marlborough Shipwrights, Havelock (south island) did an awesome job on my brothers catamaran. cheers
  8. Hi, And I started my keeler racing "career" on Notre Dame. I think they had names beginning with N tb
  9. Don't know about current price, talk to your local steel supplier. Price is very much determined by quantity also. But note that in NZ anyway, is more likely to be 1.2 x 2.4 or 3.6m and possibly even a soft conversion from 3/16, 1/4, 5/16 inch thickness. .cheers Tb
  10. Hi martin, I built one of those many tears ago from 4mm ply. I didnt glass it so eventually (after 20years) it rotted through the bottom. Was very stable, I could stand up just inside the gunnel and it rowed like a witch with one person, but was slow with any more. Weighed next to nothing. Cheers
  11. Try Lloyd Price at sounds shipwright services, Havelock. Does a superb job in my experience. https://www.soundsshipwrightservices.co.nz/. 0272438047. Has haul out and two big sheds. TimB
  12. Hi Martin, "Good idea, only snag is that there is no way to get to the top of the mast to..." Does that mean the mast is already up? If so why why can't it be lowered using the spinnaker halyard. it doesn't matter if it doesn't go to the top. I assume you mean because the main halyard is no longer there and that's the only way to get right to the top. I assume also your spinnaker halyard exit is well down from the top so you cant reach the main halyard exit if you went up on the spinnaker halyard. I see a couple of options, 1) a 15m cherry picker (commonly called a boom lift )
  13. Hi Martin, Can you stand the mast up on the boat with some temporary arrangement (spinnaker halyard maybe). Then use a bicycle chain on the end of your mouse line and feed it down from the top. The chain goes over the sheave easily and has enough weight to pull the mouse line down. You will have to go up the mast of course (on the spinnaker halyard??) and have someone catch the chain and pull it out of the halyard slot, with a piece of wire with a hook on it. If you don't trust the spinnaker halyard you could easily rig up a temporary hoisting rig tied around the top part of the mast
  14. Well that didn't prompt anything, not even the obvious 9 hours to Te Kouma for Sundreamer, it was actually more like 2 hours. I though Puff might have jumped on that. Tb
  15. The NZMYC used to keep track of these because it mattered to them. Long time since I was involved but we used to have records for the two courses mentioned by waikore plus round waiheke, The Balokovic, the triangle that went round the islands off Te kouma, flat rock and back. Akl to Tauranga etc. Sundreamer once held the te kouma record at around 9 hours, i think, Afterburner had most of the others. This is before Vodafone/Frank racing appeared on the scene. Since then the idea seems to have kind of died, no competition i guess. Maybe this will prompt some memories from someone??? C
  16. Should be less solid water over boat when flying/foiling if that is what this new boats is supposed to do. Still has drag several tonnes of lead with them so not so easy to fly. tb
  17. Dont know about anti foul but I believe the anodes will "settle down". You will have to replace them early, maybe 6 months, first time then the residual currents all find their happy places. No idea idea why technically, just know from experience. Tb
  18. and another point is that the mast and rigging on a yacht provides a helluva lot of windage, you will motor a whole lot faster for the same revs without the rig standing up, ie assuming you are trying to get somewhere after dropping the mast. Only problem is a yacht will be bloody uncomfortable without the roll slowing affect of the masts inertia.... unless it is a catamaran. No cats (or tris) in RNI unfortunately, but that is another thread topic Tb

    NRC on fan worm

    Today from Marlborough Council. I wonder if they apply this to the fishing fleet and the log ships coming into Shakespeare.... I doubt it. Marlborough Marinas Visitor Ruling May 2019.pdf Tb
  20. "Upwind would be damn near possible to point" Surely that is meant to be IMpossible? tb
  21. I would have thought the topmast runner would better a better support for the mast if it attached to the rear beam perhaps in line with the inside of the cockpit. the gennakers pull forwards as much as sideways. It would need a tweaker to pull it forward it out of the way when not in use though so much more complicated. Tb
  22. NZtiger, its a breakage issue..... when the main is reefed to or past the second reef the rig becomes a "masthead with no lowers". So the middle of the mast is unsupported (backwards) and can easily invert, pop backwards and in the extreme break. the temporary inner forestay stops this. it also stops the mast from bowing back which increases the mainsail draft, which you don't want when reefed this far. flat as possible is best. cheers tb

    Forestay cleat

    Cep, The flying Dutchman worlds are in Nelson right now, so there is 40 odd FD's there right now.. Have a look at their set up. They run the jib on a separate wire to the forestay and adjust the tension lots during the race, ie tighten up for up wind and slacken it right off down wind. Most of the guys are pretty keen to talk about their boats.. cheers Tb
  24. And vertical not angled out on a leaner???
  25. Hi Randii, In the early days some mast extrusions (which is what your beams are) were made in two pieces because the Aluminium company didn't have the capacity for larger dies. So they made some sections in two pieces with a stepped edge so they could be sort of clipped together, then riveted. Later the masts were made in one piece. Some really big ones were still made that way until recently. They are almost all carbon fibre nowadays. Tb
